[转]Java Web工程目录结构

Deadly 提交于 2019-11-30 06:10:30
说明 介绍java web 工程的基本结构目录。记录java web 工程结构的学习。 Java web 结构 java web严格来说分为两类工程结构:一个是工程编译目录结构,一个是工程发布目录结构。工程发布目录结构结构,为servlet容器加载web应用的统一标准目录,而工程编译目录结构是为了方便工程编写、修改的临时结构,需要通过工程构建工具(ant,maven,gradle等)编译生成最终的运行时发布结构。因此,工程编译目录结构并不统一,与所使用的编译工具有关(也和配置有关)。 工程发布结构 这个也是最终的工程目录结构,结构示意如下: -helloapp -index.html -othersDirs -*.html -*.css -*.png - ...... -WEB-INF -web.xml -classes -pakageName -*.class -lib -otherConfigfile -META-INF -MANIFEST.MF 如上,一般可以将其分为以下几个部分内容: 静态文件资源 静态文件资源包括需要访问的jsp、html、css、js、png、ico、gif、conf配置文件等,可以将其放在任意位置,一般默认是防止主目录下,访问后缀路径为文件相对主目录路径。如上,index.html的相对访问路径为: /index.html ,绝对访问路径为: http

创建日期 7.14 注意点: 1.document.getElementById(id).value和innerHTML都是获取内容: value用于表单,innerHTML用于<div><p>等标签 参考: https://zhidao.baidu.com/question/293791190.html 2.在function函数内,request.getRequestDispatcher("/WEB-INF/pages/login.jsp").forward(request, response)无法实现页面跳转。 3.问题(未解决): login.jsp放在WEB-INF内时,window.location.href="WEB-INF/pages/login.jsp"无法实现跳转 所以,login.jsp直接放在WebContent下, 用window.location.href="${pageContext.request.contextPath }/login.jsp"实现跳转。 4.${pageContext.request.contextPath}和${request.ContextPath}的区别: JSP的内置对象有request对象和pageContext对象,EL表达式的内置对象只有pageContext对象。 不方便区分的话,直接全用前者 https:/

Prevent direct access to composite components by placing them inside /WEB-INF

只谈情不闲聊 提交于 2019-11-29 15:24:44
I'm trying to define some composite components in my web application. According to the tutorials i read, i have to place the xhtml files inside a resource folder located in webcontent. This solution is problematic, given that it would make those files available for public access from an url. Is there a way to put this components inside the web-inf folder, and make the jsf look for the files there? If not, is there another way to avoid direct access? Thanks. P.S.: I have looked into this answer , and if i understood BalusC's answer correctly, what I intend to do is possible. "Composite

How to get properties file from /WEB-INF folder in JSF?

I have some properties file in /WEB-INF . And I want to load it in a JSF managed bean. Is there any way to do that? BalusC Use either ExternalContext#getResource() or ExternalContext#getResourceAsStream() wherein you pass the webcontent-relative path. E.g.: ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext(); Properties properties = new Properties(); // ... properties.load(externalContext.getResourceAsStream("/WEB-INF/file.properties")); This delegates under the covers to ServletContext#getResource() / getResourceAsStream() .

使用JREBEL插件包实现myeclipse修改类文件后无须重启

作为开发者,大家在做javaweb项目如果遇到 修改后台java类 的情况时经常须要重新启动服务器例如tomcat。在改动频率比较少的情况下还好说,在改动比较频繁的情况下 ,则会拖慢项目的开发进度。网上关于这个问题的解决方案已经有很多,本人现提供自己常用的一个方案如下,希望给大家带来方便。 启动myeclipse,在菜单栏上点击 windows,在弹出的菜单出选择 Preferences将会弹出如图所示的窗口。 在左侧的 MyEclipse 树形下找到 Servers(服务器)结点,根据你的项目来搭配相应的服务器。 现以tomcat 6.x为例,点选JDK,然后在右侧 找到Optional program arguments文本框输入下面的语句: -noverify -javaagent:E:/jrebel.jar -Drebel.dirs=C:/Users/lenovo/Workspaces/MyEclipse 8.5/dangdemo/WebRoot/WEB-INF/classes -Drebel.struts2-plugin=true 其中:"noverify -javaagent”是参数; E:/jrebel.jar 是jrebel.jar的存放地方 , -Drebel.dirs=C:/Users/lenovo/Workspaces/MyEclipse 8.5

What difference between app-inf and web-inf folders in JavaEE applications?

懵懂的女人 提交于 2019-11-28 18:01:42
Can you give me understanding of main difference between APP-INF and WEB-INF folders in javaEE applications. Thanks APP-INF In an enterprise application (EAR application) which contains many war and jars (eg.WebApp1.war, WebApp2.war, EJB1.jar and EJB2.jar.) and suppose all these Modules want to use some classes which is available as part of a Jar (common.jar). So in this case it is better to Place this jar file inside under “APP-INF” directory,that why we don't need to put the same Jar 4 times inside each and every Modules. WEB-INF WEB-INF is a directory that is a private area of the web
